Week 7 IT 24

1

• Week 7 IT 24
• Morphemes which add a number meaning
• This teacher led activity aims to introduce
  children to prefixes which carry a meaning
  related to number.
• At the start of the presentation, pictures of
  cycles appear with different numbers of wheels,
  and these are linked with the prefixes uni bi
  and tri.
• Teachers will need to give an explanation to go
  alongside this, to explain that some beginnings
  of words give a clue about number e.g. triangle
  means 3 sided.
• The answer sheet (see next slide) needs to be
  printed off and given to the children prior to
  the lesson.
• Further number morpheme words are given, and
  children are asked to write how many is meant
  by the prefix each time. This is prompted by the
  appearance of a pencil.
• Children are asked what gave them the clue for
  this number and feedback is then given on screen
  of the prefix and its number meaning, and a
  picture of the word appears e.g. unicorn,
  tripod.
